Split Personality (Gimmicks and Online Instructions) by Wayne Dobson - Trick

The premise is easy...

The magician displays two sets of cards and a prediction. One pile is of last names of famous people and the other pile is of first names.

The magician shows some of the cards and, from the first or last name, the spectator guesses the celebrity.

The cards from each pile are given to the spectator to shuffle and the top card from each pile is turned over. Unfortunately, the names don't match up and reveal the name, "Charlie Monroe." The trick has appeared to have gone wrong.

However, the magician turns over the prediction card to reveal Charlie Monroe an amusing photograph image of the two famous icons morphed together!
